WalkthroughThe dashboard now divides TPS counter deltas by the elapsed time between samples. Tests check normalized reducer output and TPS values when polling is delayed. ChangesTPS normalization
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: ⚪ Minimal · up to This change makes the "Transactions per second" dashboard chart correctly divide by the actual measured time between samples instead of assuming the configured refresh interval, fixing inflated/deflated TPS readings when polling is delayed or throttled. Verification of the preference-change reset path and first-sample behavior found no new correctness issues introduced by this change, so it appears safe to merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

- Line 183: Update the tps_stats_refresh preference-change branch to clear
counterData['tps_stats'] along with the TPS history before the next
tpsStatsReduce call, ensuring the first value uses a fresh baseline and the new
interval. Add a regression test covering this refresh-interval transition.

Changing the tps_stats_refresh preference reset the displayed TPS history but kept the previous absolute counter reading, so the next delta was computed against a stale baseline whilst being divided by the new interval, mis-scaling the first post-change data point. Addresses CodeRabbit review on pgadmin-org#10324 (issue pgadmin-org#10273).

The new test exercises only
statsReducerwithrate: 5. TheGraphstests disable polling, and the non-default preference test asserts only the poll delay. A regression that removesrate: preferences['tps_stats_refresh']from thetpsStatsReducecall can therefore leave the tests green while the chart displays a raw counter delta instead of a per-second value. Add a component-level test that supplies a non-1-second refresh rate, processes TPS data, and asserts the chart data is normalized.🤖 Prompt for AI Agents

The configured tps_stats_refresh value is the requested interval, not the time actually elapsed between two counter samples, so a poll delayed by browser timer throttling overstated TPS. Each TPS sample is now time-stamped when its request is sent and the delta is divided by the measured elapsed seconds. Because the baseline carries its own timestamp, a change of refresh interval, or a response from a request made before that change, no longer mis-scales the next value, so the baseline reset on preference change is no longer needed. Adds a component-level test driving the poll path with a 5 second refresh and a delayed poll. Addresses CodeRabbit review on pgadmin-org#10324 (issue pgadmin-org#10273).

The Transactions per second chart plotted the raw xact_commit/xact_rollback delta between two polls without dividing by the elapsed time, so the value was only correct when the refresh interval was 1 second; at any other interval it showed transactions per interval instead of per second.
